Bok! If anyone had asked me the 'outsourcing' question I'd assume that they don't really understand how difficult it is to actually build a business. Furthermore, I'd assume that the person asking me that question, didn't attain their wealth by starting and growing their own company (which would lead me to other questions).
However the question "What if someone copies your service, and offers it half the price?" is an excellent one and is basically getting at what your advantage is. It's not the same as 'outsourcing' in my mind.
You should also bear in mind that you should be testing the investor also. It needs to be a two-way street unless you're only after 'dumb' money (although dumb money probably comes with dumb advice too).
